AUTOMOBILE-TIRE.

Specification of Letters Patent.

Patented May 31, llO.

Application filed May 27, 1909. Serial No. 498,668.

T o all whom it may concern:

Be it known that. I, Howano S. SHA1-m2, a citizen of the United States, residing at Nazareth, in the county of Northampton and State of Pennsylvania, have invented certain new and useful Improvement-s in Automobile-Tires; and I do declare the following to be a full, clear, andexact descrip tion of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in automobile tires.

The object of the invention is to provide an improved. construction of tire having means arranged therein to prevent skidding or slipping of the tire andY also to preventthe uncturing of the saine.

ith the foregoing and other objects in View, the invention consists of certain novel features of construction, combination and arrangement of parts, as Will be more fully described and particularly pointed ont in the appended claim.

In the accompanying' drawings, Figure l is a perspective view of a section of tireconstru'cted in accordance With the invention; parts of the same being broken away; Figl- 2 is ay transverse sectional View of the same; v

Fig. 3 is a transverse or horizontal sectional v1ew through the outer portion of the tire, showing the arrangement. of the anti-skidding rivets whereby-they servey to prevent punctnring the tlre.

My improved tire comprises a body portion l formed of rubber or other suitable composition and has molded or embedded therein adiacent to itsy inner surface an armor 2 formed of woven wire, through the loops or coils of which are diagonally arranged wires 2l, which extend to the inner edges of the tire and are looped around fastening rods or wires 4 arranged in the. edges of the tire, as shown. The edges of the tire may be of any suitable shape to engage the style of rims o which the tire is to be placed. The ti e is preferably provided with a lining 5 formed of several layers of 'canvas'orotherv suitable fabric.

I n the .tread portion of the tire is arrivets Gand 7said rivets being molded or vulcanized in the 'tire when the latter is l l l l i i, i i i i l formed. The rivets G are of greater length than the rivets i, the heads of the rivets 6 being disposed in a plane immediately belo'w the heads of the rivets 7 and the heads" of the rivets 7 are so arranged as to practically cover the spaces between the heads of the rivets (i, thereby forming an outer armor for the tread portion of the tire. which will prevent the puncturing of the same by any sharp objects over which the saine may pass. The outer ends of the rivets '6 and T extend through the tread portion of the tire and are flush with the buter surface thereof and serve to prevent the lateral skidding or slipping of the tire. It Will thus be seen. that the rivets 6 and 7 serve the two-fold purpose of providing an armor for the tire as well as providing means to prevent the skidding or slipping of .the same.

From the foregoing description, taken in connection with the foregoing description, the construction and operation of the invention will be readily understood without requiring a more extended ex lanation.

Varlous changes in the orm, proportion and the minor details of Aconstruction may be resorted to Without departing from the principle or sacrificing any of the advantages of the invention, as defined in the appended claim.

Having thus described my inventiomwhat I claim is:

A tire provided with anti-sltidding and puncture-proof means comprising a series of rivets molded in the tread portion of the tire with their heads disposed beneath the outer surface thereof and their stems extending z iiush with the outersurface, and other se. t ries of longer rivets arranged in the tread portion of the tire with their heads disposed beneath and alternating with those of the -iirst-mentioned rivets and their stems ex tending flush with the -outer surface of the tread portion. I

In testimony whereof l have hereunto Set my hand in presence of t'wo subscribing wit nessus.
